` `Application led August 19, 1812. Serial No. 715,897.

` a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Ventilators; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompa- .nying drawings, and to the letters and f iguresl of reference marked thereon, which form a part of this specification.

My invention relates to ventllators, and more particularly to a device of that type which is adapted for confinement wrthln an opening in a window sash., the principal Iobject of the present invention being to provide a ventilator of this type having an adjustable door member for regulating the air intake and having screens for filtering the air during its passage through the ventilator. In accomplishing this object, I have provided the improved details ofstructure hereinafter described and illustrated in the accompanying drawings, Wherein:-

Figure I is a perspective View of a window sash equipped with a ventilator constructed according to my invention. Fig. II is an enlarged cross-section of the sash andfventilator. Fig. III is a detail perspective view of the outside ventilator box. Fig. IV is a. similar view of the inside box. Fig. V is a vertical section of the sash on the line V-V Fig. II. Fig. VI is a similar view on the same line, but looking in the opposite direction to show the front box from the rear. Fig. VII is a detail view of part of the back box showing the screen lip. Fig. VIII is a similar view of thefront box showing t-he clip for the front. screen.

Referring more in detail to the parts: l designates a window sash having an opening 2 extending longitudinally therein. Ex-

tending into the opening 2 from the outside' of the sash is a box '3 having an opening 4 extending longitudinally in its lower portion and having closed ends 5, the inner edge of the upper portion of the box having a depending lip 6 forming a trap 7 for the rear screen, and the lower end of the box having vertical corrugations 3 n which the ventilator may be drained, when drainage is required. Rising from the l with through lower edge of the box is a icurved deiector 8 which terminates about the center 'of the box, and has a back-turned lip 9 Which is slit at intervals throughout its length to provide lips 10 which are curved forwardly of spring clips for supportlng the rear screen and holding same in place. The rear screen comprises a frame l1 which is adapted to project through the opening between the upper box lip 6 and the `forward edge of thedeflector 8, so that when its upper edge is in the corner of the box, its lower edge can be sprung over the clips 10 to seat on the back-turned lip 9 and on said clips.

Seated in the front of the opening 2 is a box 12 having an opening 13 throughout substantially its entire length and wldth the l lower edge of the box being slit to form the lips 14- which are turned forwardly and upcurved to support a front screen 15. The inner edges of the box at the ends of the opening are also slit and turned back to form the lips 16, for engaging the ends of the screen when the latter' is projected into the box. Between the lips 16 and the ends of the box are vertical slots 17 through which the friction latch plates on the front door are projected, as will presently be described.

i he box l2 is held .within the sash opening by a collar 18 having horizontal fianges 19 overlaying the inner faces of the box 12, and vertical fianges 20 which project over the face of the sash at the edges of the opening 2, the exposed flanges being provided with apertures through which screws, or the like, may be projected into the sash to hold the collar in place. The upper horizontal flange 19 of the collar is slit in line the lips 14, and turned downwardly to form the upper spring clips 22 for holding the upper edge of the front screen. As the front screen is held in place by the lips 14 and 16 and clips 22, past which the screen is projected'to gain its seat, I providethe screen with iinger holds 23, preferably constructed as lips, formed integral with and projecting inwardly from the ends ofthe screen rim in front of but spaced from the screen, so that a person wishing to insert or remove the screen may grip the finger holds and thereby easilyhandle the screen.

Fixed in the ends of the collar 20 at the lower front portion thereof is a rod 24, and

Y angular in shape and adapted for projection arated from the bodg o 1y j justedy position, tween the ends Uthe ing'er holds thereon and outer screen being revolubly mounted on said ro'd is a sleeve 26 which carries a front door 26 preferably formed of sheet metal and adapted to completely close the box 20, the upper edge of the plate being provided with a yrail 27 which, may overlle the upper edge of the box and serve as a stop to limit the inward travel'thereof. Fixed to the inner face of the door adjacent the ends thereof are the latch plates 28, which are substantially triinto and travelthrough the slots 17 at the ends of the inner box 12. Near'the edge of eachplate 28 is a stri 29 which is septhe plate by a slot 29'- and has outwar projecting corrugations 30 adapted to wipe the inner faces of the ends of the kee er collar,so that they will frictionally hold the door at-any adthe plates projecting beends ofthe sash opening when the door.. is closed. I also prefer to provide the door 26 witha damper plate 31 whichA may be manipulated by a knob 32 which projects through the door to the outer face thereof.

In vusing the boxes are fixed in place, the inner box being held in position by'its collar and the outer screen 1s projected Ithrough the inner box and seated 1n its trap by projecting the outer end vinto the u per corner of the box 3,)and by -pushing' t 'e lower end over the spring clips 10, so that it may gain its seat and be yieldingly held in place therein. The

Y' inner screen is then projected through the inner NAface of the opening and the lips 14 and 16 and spring gain its seat over the opening in the inner box. The front door may then be inclined to regulate the amount of draft therethrough and deflect the air upwardly into a room, or the door may be entirely closed and the Vintake of air regulated by means of the damper. By having the outer screen set at an incline above the stationary deector, dust thrown upwardly by the stationary member will be deflected against pushed past the back of the trap and fall back through the opening in the rear box.

When the ventilator is to be cleaned, the inner screen may be removed by grasping pulling the screen outwardly past the spring clips, the

also removable by pulling the inner end `ver the clips on the del flector and removing same through the in- A ner box. It is apparent that should either of the screens be left out, the air may still be filtered by the other screen during its travel through the ventilator. Itl is also apparent that should .a hard storm vdrive rain up through the outer box into the interior of the sash, it may drain through the 65 vertical corrugations 3.

A screen covering of the door box 3 and theV device, the inner and outer' clips 22 vto Having thus described 'my invention, what I claim as new therein and desire to secure by Letters-Patent, isz- 1.
